HORSESHOE.

$PEGIFIGATION forming part of Letters Patent No. 412,709, dated OctoberS, 1889. Application filed March 31 1888. Renewed February 28, 1889. Serial No. 301,583- (No model.)

i To all whom it may concern.-

.shoes in which a false shoe composed of one or more pieces and having calks integral therewith or removable therefrom is secured to a main shoein such a manner that the false shoe and calks forming a part thereof or secured thereby may be removed from such main shoe without taking said main shoe from the hoof to which it is nailed.

. The purpose of myinvention is to obtain a firmer and better-manner of attaching the false shoe or the pieces constituting such false shoe, if it be made of more than one piece, and the calks to the main shoe to obtain complete protection to the'frog of the foot from nails, rocks, and other obstructions, while at the same time air is allowed free access to the frog of the foot, and also to obtain a cast metal main shoe, to which said false shoe may be secured, having nail-holes and grooves in which said nail holes are placed formed in the casting of the said main shoe in such location upon said main shoe-andat such an angle with the plane of the surface of the shoe coming in contact with the hoof that the nail inserted through any one of the said nailholes shall be in proper place and guided in proper direction in the hoof, so that such main shoe may be secured to the hoof by a person not skilled in the art of shoeing horses.

In this specification, for convenience, I term the face of the main shoe, placed against the hoof, the upper side? of the shoe, and the facecomingin contact with the ground, or with the false shoe, when one is attached thereto, the under side of said shoe.

I have illustrated my invention by the draw ings accompanying this specification and forming a part hereof, in which-- Figurel is a front-plan view of the shoe; Fig. 2, a back plan view; Fig. 3, a cross-section on line 3 3 of Fig. 1, and Fig. 4 a crosssection on line 44 of Fig 1. In Fig. 5 W X Z are sectional views on lines l/V X Y Z of Fig. 2.

Like letters refer to like parts throughout the several views.

A is the main shoe, secured to the foot in the ordinary manner by nails. ShoeA has a portion of its upper surface taken away, forming bevel a, and has also notch a on each end thereof, said notch a forming a lock for bar B when said bar is pressed firmly against said notches.

B is a bar having. a groove at each end thereof (lettered 1),) and having calks B B thereon, integral therewith. On said bar B there are also lugs or raised parts b, having a hole or groove 1) b therein. Either a hole or a groove b" may be used, each performing equally Well the same function. I have therefore lettered them alike. Through this hole or groove 1) wire C is driven into holes e in lugs e on plate E, hereinafter described.

D is a bar having groove 61 around the outer edge thereof. This groove d, as also grooves 12 b on bar B, fits upon or over the bevel a in shoe A when said bars B D are pressed firmly in proper position. In bar D are holes 01 d on that edge of said bar in contact with plate E when all the parts forming the false shoe are secured in position on the main shoe A. Bar D has thereon calk D, integral therewith.

E is a plate havinglugs e e at one end thereof, with holes 6 e in said lugs, and lugs F F at the other end thereof, with pins or projections ff integral with or firmly secured to said lugs F F. Plate E overlaps upon its sides upon the under surface of main shoe A, and it is made of such length that its ends may pass upward into place between bars B and D, thereby pressing said bars firmly into position and locking them on main shoe A. The lugs e e and F F on plate E come in close contact with lugs 79 b on bar B and one edge of said bar B and with one edge of bar D, re spectively, and when plate E is pressed upward, as hereinbefore described, into place, so that the upper surface of said plate E is in contact, or nearly so, with the under surface of main shoe A where said plate overlaps said shoe, the bar D and bar B being pressed apart and firmly into position, the said lugs and said edge of bar B and bar D are in close contact. When in this position, said bars B and D being locked on main shoe A, and bar B being also looked on notches a a of said main shoe as well as by grooves Z) Z) on said bar B fitting over the beveled edge of the main shoe, the heel of said main shoe is prevented from spreading and said bars B D are firmly secured to such main shoe.

That feature of main shoe A and bar B represented by the locking of said main shoe A to said bar B bynotches a a and the bar B is more fully set out and described and claimed in application Serial N 0. 261,099, made by me on the 10th day of January, 1888, and this device, with such other, if any, as may be herein described or illustrated in the drawings accompanying this specification, is not herein claimed where the same is described and claimed in the application already made.

On lugs F F and integral therewith, as already stated, are projections f f, entering holes d d onbar D, and the end of said plate E is thus held firmly in position; if the other end of said plate E be pressed into position and there held by pins 0 O, driven through holes or grooves b" b in lugs 12 b and holes e e in lugs e 6. Bar B, having calks thereon, bar D, having a calk thereon, and plate E,- all constituting the false shoe, are thus firmly attached to main shoe A.

To remove the false shoe so formed by bars B and D and plate E from the main shoe A, it is merely necessary to drive pins 0 Centirely through holes or grooves b b in lugs b b, when the end of the plate E in contact with bar B may be withdrawn therefrom and said plate removed. Bars B and D may then be removed, and new bars,- duplicates thereof, may be put on said main shoe.

Strengthening-bar G may be placed on plate E integral therewith, if desired.

That part of my invention relating to the manner in which the nails securing the main shoe to the hoof are located and guided, so that both main and false shoe maybe secured to the foot without the aid of one skilled in the art of horsesho'eing, is more particularly illustrated in Figs. 2 and 5, and the descrip tion thereof is as follows:

Groove A, in which the nail-holes are put, is formed by taking away the metal of the main shoe, or by casting said groove A in said shoe, so that the under side of the groove is described by line K K K" K at the point in said groove where the several nailholes are placed, and the side of said groove A is described by lines H H H H at said points in the main shoe. The nail holes lo cated in said groove A are described by said lines H H H H and lines I I I 1 upon the'sides of said holes, the ends thereof being substantially parallel with each other and at right angles to the upper surface of the shoe.

It will be observed by a comparison of lines H H H 11, forming, respectively, one side of the several nail-holes, the said lines also forming one side of the said groove A at the place where the several nail-holes are placed, respectively, that each nail inserted in said holes is guided at a different angle into the hoof from all other nails upon the same side of the shoe. This inclination is the better observed by a comparison of said lines H H H H with dotted line 7c. The lines H H H H on the under surface of the shoe (the top side in Fig. 5) are at the same distance, or nearly so, from the edge of the shoe, while upon the upper surface of the shoe the said lines are at a Varying distance from said edge. The line H being the side of the hole nearest the toe of the shoe, is the farthest in from said edge, the distance gradually decreasing to the hole at the heel of the shoe; The depth of groove A, in which the nail holes are placed, is the same throughout the entire length of said groove, ornearly so, the opening of the nail-hole on the upper side of the shoe being in every instance of substantially the same size. The inclination of the lines I I I I also varies, and-therefore the inclination of the line forming the bottom of said groove is constantly varying, the incli nation thereof at the several nail holes being shown by lines K K K K. Dotted line 70 k of Fig. 5 illustrates the difference in the direction of lines I I I" 1 when compared therewith.

By inserting a horseshoe-nail in any one of the holes hereinabove described proper location and direction is given said nail by the position of said holes and the inclination of the sides thereof, so that said nails may be properly driven bya person having but little skill in horseshoeing, and I thereby obtain a main shoe of the character described, which may be secured to the hoof without taking the horse to a regular horseshoer, and the calks may also be easily inserted or seenred to said main shoe by the false shoe hereinabove described, forming part of my device.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is'

1. In a horseshoe, the combination of a main shoe,a grooved bar forming heel and toe bars attachable to said main shoe, said b'ars having calks integral therewith, with a plate overlapping at the sides thereof onto said main shoe and pressing between said heel and toe bars at the ends of said plate, and means for securing said plate in position, all substantially as described. Y 2

2. The combination of shoe A, having beveled edge a and notches a thereon, with grooved bars B D, having calks" thereon integral therewith, plate E, having lugs e e F F thereon, pins 0 O, fitting into holes in lugs e e on said plate and into holes I) on bar B,

and pins f f, integral with lugs FF on plate E and'fitting into holes in bar D, all subeled faces of the groove the sides of said nail- 10 I holes, the ends of said nail-holes being parallel, and the said nail-holes having openings on the upper sides of said shoe of equal size.
